Recycling of Materials from Renovation and Demolition of Building Structures in the Spirit of Sustainable Material Engineering

Abstract

In the European Union, more than 20% of residential buildings were constructed prior to 1945 and are approaching the end of their projected lifespan. This necessitates renovations or demolitions of these structures. A study was conducted to analyze the quantity of waste generated during the dismantling of a representative building from that era. Construction waste is produced during the building process and its disposal can be costly. Sustainable material engineering offers a solution by promoting the reuse of waste materials. When designing new products, manufacturers should consider using waste materials and ensure they have an extended lifespan, efficient life cycle management, and sustainable consumption. A study has shown that researchers are currently exploring the potential use of waste steel, bricks, wood, and glass in composite materials. Direct reuse of waste in the construction industry has also been observed. However, users’ preferences show that while environmental concerns are important, good quality and price are still the primary factors that drive consumer demand. Therefore, materials made from waste materials must demonstrate excellent parameters to gain consumer acceptance. Education initiatives such as green building certifications and education programs for construction professionals and the general public can help promote sustainable practices. Despite progress made in sustainable development, there is still a need for further education to encourage the adoption of sustainable practices.
